TDK introduces a new EPCOS NTC sensor element

     TDK Group introduces a new EPCOS NTC sensor element designed for measuring high temperatures up to 650 °C. The element is based on a high temperature ceramic sensor element, connected to a metallized alumina rod and then enclosed in glass, with high measurement accuracy and a temperature tolerance of only ±1 K at 200 °C. Thanks to the glass package, the new component is extremely robust. The new sensor is 16 mm long, has a glass package with a diameter of 2 mm and is also equipped with a connection wire welded to an alumina rod (optional).

     The AEC-Q200 compliant high temperature sensor is designed for demanding automotive electronics applications such as exhaust gas recirculation systems. Mainly used in diesel engines, it can reduce the excess oxygen in the combustion gas, so that the nitrogen oxides produced at high combustion temperatures are minimized. In the recirculation system, the NTC sensor measures the temperature of the exhaust gas, helping to prevent engine overheating, especially the cylinder head and seat.

     In electric vehicle applications, the new sensors can monitor the temperature of fuel cells used in electric vehicle drive systems (which produce electricity directly from hydrogen), and can also be used in household appliances such as self-cleaning furnaces (which work on the principle of pyrolysis). The self-cleaning stove works by heating the body to 500 °C, breaking down the long-chain molecules of the food residue, turning most of it into gas and ash. The NTC sensor adjusts and stabilizes the desired temperature.
